Electrochemical Properties of (η5-C5Me5)-Rhodium and - Iridium Complexes Containing Bis(pyrazolyl)alkane Ligands
| Resumo: | The electrochemical properties of rhodium(III) 1-3 and iridium(III) 4-6 complexes containing bis(pyrazolyl)alkane ligands [MCp*Cl(R2C(3,5-R'2pz)2)]X (M = Rh (1) or Ir (4), R = R' = H, X = Cl; M = Rh (2) or Ir (5), R=H,R'=Me,X=Cl;M=Rh(3) or Ir (6), R=Me,R'=H,X=OTf;pz=pyrazolyl;Cp*=η5-C5Me5) were investigated by cyclic voltammetry and controlled potential electrolysis. They exhibit two sequential irreversible reductions assigned to the M III → M II and M II → M I reductions, which are dependent on the methylation of the bis(pyrazolyl)alkane ligands. |
